Melting Glaciers Are Causing the Ocean Floor to Sink

The added weight from melting land ice has depressed the seafloor about 0.005 inches annually between 1993 and 2014, demonstrating the large-scale impacts of climate change.

Linear trends and accompanying 1σ confidence intervals resulting from ice mass and LWS changes over 1993–2014 in (a) solid Earth deformation over the oceans, (b) relative sea level, and (c) geocentric sea level. Note that geocentric sea level change is equivalent to the sum of relative sea level and ocean bottom deformation change. The blue line depicts the line where local sea level change is equal to the ocean mean sea level trend, whose value is written in blue under each map. | Geophysical Research Letters
